SUMMARY
=======
When creating an XY Scatter chart using the MSChart control, the resulting chart
may appear distorted; that is, very tall and narrow or very short and wide. This
occurs on an XY Scatter chart whose axes have ranges that differ by a large
amount. For example, an X axis with a range of 0 - 10000 and a Y axis of 0 - 50.
MORE INFORMATION
================
By default, the scale on the axes of an XY (Scatter) chart is uniform. If the
x-values are small in comparison to the y-values, or vice versa, the chart may
appear distorted. To allow the scaling of each axis to be independent, change
the UniformAxis property of the Plot object to False. The default value of this
property is True.
Step-by-Step Example
--------------------
1. Start Visual Basic and create a new Standard EXE project. Form1 is created by
default.
2. Click Components from the Project menu and check the "Microsoft Chart
Control" component. The MSChart control is made available on the Toolbox.
3. Put an MSChart control on Form1.
4. Copy and paste the following code to the form's code window:
Private Sub Form_Load()
Dim Graph(1 To 10, 1 To 2) As Single
Dim x As Integer
For x = 1 To 10
Graph(x, 1) = x ' value for X-axis
Graph(x, 2) = x * 10 ' value for Y-axis
Next x
MSChart1.chartType = VtChChartType2dXY ' set to X Y Scatter chart
MSChart1 = Graph ' populate chart's data grid using Graph array
' Leave the following line commented until step 6:
'MSChart1.Plot.UniformAxis = False
End Sub
5. Press the F5 key to run the project. Note that the chart is not legible (tall
and narrow) because both x and y axes are using the same scale and the
y-values are larger than the x-values.
6. Stop the project and remove the comment on the last line of code.
7. Press the F5 key to run the project, and note that the chart is legible.
